I have a quick question regarding DVD/CD audio connection to the 990:

I am using the optical (toslink) ports to connect my DVD player (Momitsu V880) to the 990. My question is: are there times when this is the wrong thing to do?

For instance, I have seen several posts where people are using a separate CD player, with analog connections to the 990 for 2 channel audio listening. Do they do this because they believe the DA conversion in the CD player is better than the 990 circuitry? Unless you're in bypass mode, isn't this analog signal converted to digital, processed (say for bass management) and then converted back to analog? Seems like using the CD/DVD player as a transport mechanism, and using a digital connection would almost always be the way to go...

What about SACD? I have a 2nd DVD player capable of playing SACD's. Would the optical out on this player enable 5.1 channel playback?, or would I need to hook up those 5.1 analog inputs?

Just curious really-
Thanks.
